This didn't happen to me, fortunately. Never had the problem (thank God!).

But I knew a guy who said he'd just had a hemorrhoid operation, and afterward, his doctor gave him a tube of soothing ointment. He got up in the middle of the night with a need to relieve himself. After he'd cleaned up, he reached behind him in his half-asleep state for the tube of ointment.

He got the tube of Ben Gay by mistake.

He said he woke up quite quickly!!
